To all whom t may com/ora:

"ie i-t known that L "Wimmer Triennio JAMES, a citizen of the United States, and a resident ot liicagrn in the county oit @ook and State or lllinoisj have invented certain new and useful linproveincnts in Wagon- Loading Apparatns7 ot which the following is a speciication. v

My present invention relates to wagon. loading apparatus, and more particularly apparatus of this kind adapted to litt ninterial from tbe gronid into a wagon by means oi? an endless coi'iwjer.

The principal objects ot my present invention are to provide 'means for bringing the material to be lifted toward tbe .lower end of the conveyor from either side 'tlfiereofg to provide means tor cutting and breaking np the material to be lifted by the con'eyer; provide impr-cred means for .connecting tlie notor operating; tbe apparatus to the various operative parte thereof; and generally, to improve, simplify and clieapen tile construction or Wagon loadi'n apparatus or the kind set ifortli.

In attaining these and certain otlier objects and advantages to be hereinafter dis closed, l have provided a construction. one embodiment ci nfl'iicli illustrated in the accompanying drawings, in Wliicli Figure l is a side elevationj partly in sec tion, oit the appz'tratus a. whole;

Figure i2 is a detailed View oit the journal ot the axle carrying the traction Wheels oit the apparatus;

Fig. E3 is a section on tl i Vline 3--3 of Fig. l.;

Figs. 4l and 5 are,respectively7 iront and tlie apparatus as a Whole.

The Wagon loading apparatus illustrated in the drawings consists oi' a traine lil. which carries the 'frame 1Q o' tbe conveyer i3. A pivotal connection is proridedbetween the frames il and i12 which will be subsequently described.

@n the Jranie "il is mounted a motor 14; preferablyv reversible by which the conveyer may be operated or the traction 'Wheels of the apparatus rotated in order 'to nieve tne apparatus as a Whole along; the ground. 'i r1 niotor M is provided with a sjjirocket 10 con nected by a chain l5 to a sprocket 1'4"' revolu- 1 paratns.

bly mounted on tbe shan; lo. 'lhe slialt 16 is the ams about Wbicli the conveyer 13 swings,

so by placing` the sprociet on the shaft lli f" no special adjustments have to be made in the power transmission gear as a result or a change in position of the conveyer, Illiis sprocket l? is provided v-:itli olntcn projections on both lateral faces, those on one race being adapted to engage with corresponding projections on tbc sproclrr-t lo' and those on 'the other tace with projections on tlie sprocket ith jln'teli operating evers i512 and are provided for bringing either oi? the sprockets 1S or i9 into engagement with the sprocket '17.

The sprocket 18 is connected by means oir a chain 20 to the sprocket 21 to which is rigidly connected. a pinion which engages the gear Wheel E23. The last-irren toned gear wheel is rigidly connected to friction Wheels adapted to be brought into engage' nt with the tread snriaccs of the traction Wheels ln order to bring the w'l'ieels Qa and. 25 into Contact, provision is made for moving the 'wheels Q5 rclativeljT to tlie traine o' the ap- '.llie preferred method of produc-- ing the relative increment is shown more particularly in Fig. 2 and. consists in pro riding an eccentric journal 26 for tbc axle 27 f" The eccentric which carries the wheels 2G is itsell` arranged 'to turn in a journal 28, and the angular position of the. eccentric relatively thereto can be varied by rneans of tire arrn Q9 connected to Ythe eccentric and the operating lever BO pivotall v conn ated to tbe end oit tbe arm 2S). lt will be apparent that by polling on tbe lerer 50 tire Wheels will 3c brought into trictionai engagement with the Wheels 2l. is the motor lfl is reversible the Wheels 2.5 can be driven in either direction at Wilt.

The apparatus can be propelled into the material that is to be loaded "into tbe conveyor while the latter in operation so that the apparatus will ont its way into the inaterial and simultaneonslj" litt tbe material into a wagon. The fractional dritre on the traction Wheels prevents severe oeerloa'ding o' the conre'yer and revolving acoops the "wheels slip as soon as resistance to 'ormird niotion exceeds a certain limit.

The rear n'lieels 5G are arranged to turn in unison for the purpose of steering the 'apparatus. The axle of each wheel 56 is pro- 1 vided with a vertical portion 57 revolublyA mounted in theframe 11 and having a projecting arm 58. rlhe two arms are connected by a suitable link 59.

F or operating the conveyer the sprocket 19 on the shaft 16 is connected by means of a chain 31 to the sprocket 32, which 'in turn drives the sprocket 33 at the lower Hend of the conveyer by means of the gear Wheels 34 and 35. To the sprocket 33 of the conveyer are connected .beveled gears 36 in mesh with the beveled gears 37 on shafts 38. These Shafts 38 carry the scoops 39 which move the material to be lifted into the wagon from the sides toward the path ot' movement oi' the conveyer.

The conveyer itself consistsA of two parallel endless chains with buckets arranged across with both ends projecting laterally. Underneath the frame 12 of the conveyer is an apron connected at its upper end to the chute L18. rlhis apron prevents material falling onto the motor and other operating parts of the apparatus.

The scoops revolve in a plane substantially perpendicular to the vertical plane of the conveyer, and the speed of revolution is timed so that successive scoops will deliver the material into successive buckets or to be picked up by successive buckets. scoops can be used to cut into clay, sand, earth, etc.

In addition to providing means for moving the apparatus along the ground and for operating the conveyer, it is desirable to provide means whereby the angular position of the frame -12 which carries the conveyer 13 can be changed relatively to the main frame .11 of the apparatus. For this purpose the frame 12' is provided with a journal 40 through which passes the shaft 16 which is attached to the frame 1l. ln order to adjust the position of the frame 12 relatively to the frame 11 a geared segment 41 is provided which is connected to the frame 12 by means of the members 42. The internally arranged teeth of the geared sector 4l are in mesh with a pinion 13 rotated by a worm wheel lll in engagement with a worm 45. The pinion i3 and worm wheel 44 are rotatably mounted on the axle 270i the traction wheels 25. The worm 45 is mounted ona shaft 46 provided with a handle i7 by which it can be readily rotated. ln this way the angular position of the frame 12 and the conveyer carried thereby can be readily adjusted by hand required.

The portions oit the apparatus required to move the apparatus into engagement with material to be lifted and to operate the lift conveyer have been described. lt has been found desirable, however, to provide The aesinet@ means for controlling the discharge of Ina'- terial from the apparatus, and for this purpose the discharge chute 48 is provided with a segmental gate 49 adapted to turn about a pivot 50. 'lhis gate is arranged so that it is lifted by the movement of a pair of levers 5l pivoted about the point 52 under the action of counterweights 53 arranged at their other end. For this purpose the gate is provided with a projecting arm adapted to be engaged and lifted by the bar 66 which connects together 'the ltwo levers 51 whenever the counterweight 53 has a greater turning movement about the shaft 52 than thebag and the parts at the other ends of the levers 5.1. These' counterweights normally hold the levers 51 in such a position that the gate is elevated, but are of such weight and are arranged at such a distance from the fulcrum 52 of the levers 51 that 1f a empty bag is suspended from the upper end of the levers 51 the effect of the -counterweights will be overcome when the bag has been lled with materiali, so that a lled bag will close the gate 49 and auto- 'matically cut oit the flow of material as soon as the bag has been filled.

The bags are suspended between the two levers 51 operating in unison by bringing the ears of the bags into engagement with the pins 67, and when the bag is full it automatically falls to the -ground level or to an intermediate platform level provided for holding or storing the bags, when the filled bag is removed and an empty bag put in its place. The levers 5l are then released when they rise until they contact with the segmental gate, open the latter and hold it open until the material has filled the bag, when the latter again goes down and the operation is repeated.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure 'by Letters Patent isi:-
